BREA, Lloyd Schwengel: Letter-writer Ed Pyle has argued that John McCain has outlived his usefulness [“McCain's final disgrace,” Letters, Dec. 3]. I, too, am a veteran – of the same war as McCain – and disagree with Pyle.

The conclusion that all the questions about what happened in Benghazi and afterward have been answered only shows naiveté. The answer to why mention of the culpability of any terrorist group was deleted from the Benghazi memo so as not to tip off a radical Islamic terror group is absolutely ridiculous.

Nearly three months after the attack left four Americans dead in Libya, we should ask ourselves just how many of the perpetrators have been brought to justice, as our president so vehemently promised would be his focus. The answer is a big fat zero.
